| Deciphering the molecular dynamics of cell-cell adhesion formation using a novel reconstituted cell surface system
| Reconstitution of the cell plasma membrane-actin cortex interface
My research interests lie in the understanding the molecular and physical principles that govern processes at the plasma membrane of cells. Particularly, by which mechanisms the force generating machinery of the cell cortex,
structural filaments and motor proteins, govern and regulate the mechanical properties of the cell membrane and dynamics of cell membrane components, and vice versa, how membrane organisation and signalling events feed-back
to the regulation of the cortex machinery. These mechanisms, which in turn regulate cell motility and cell-cell interactions, underlie important, poorly-understood human diseases that constitute global health problems.
The lab employs novel assays based on reconstituted membrane systems in combination with measurements on live cells using state of the art fluorescence microscopy and mechanical manipulation.
